Problems solved by technology

[0002] At present, the moisture in the soil is mostly detected by the moisture detection sensor. The sensor is buried in the soil. In order to detect the moisture content of the soil at different depths, it is usually necessary to bury a sensor at different depths. This method requires digging a large hole in the soil. , arrange multiple sensors along the vertical direction on the cross section of the pit, the operation is difficult, and the number of sensors is large, and the detection cost is high

Abstract

The invention relates to a moisture detection device, which comprises a strip-shaped detection body with a sealed accommodating cavity inside, and a strip-shaped through-hole is opened through the side wall of the detection body, and a protection device that can block the soil is arranged at the through-hole. A protruding ring protrudes from the wall of the housing cavity, and the protruding ring is arranged around the circumference of the through hole. The end of the protruding ring is sealed by a waterproof flexible film layer. The flexible film layer is not stretched straight. A guide rod is provided, on which a sliding seat slides, and a rack is provided on the side of the sliding seat close to the flexible film layer. The lengths of the guide rod and the rack extend along the length direction of the detection body, and the sliding seat is far away from the rack. A sensor for detecting moisture is installed on one side, and a gear and a rack are arranged in the accommodation cavity, and the flexible film layer is located between the gear and the rack. A control main board is also installed in the accommodation cavity, and the sensor and the driving part are electrically connected to the control main board. . The moisture detecting device of the invention has low cost and is easy to install.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a moisture detection equipment. Background technique [0002] At present, the moisture in the soil is mostly detected by the moisture detection sensor. The sensor is buried in the soil. In order to detect the moisture content of the soil at different depths, it is usually necessary to bury a sensor at different depths. This method requires digging a large hole in the soil. , a plurality of sensors are arranged in the vertical direction on the cross section of the pit, which is difficult to operate, and the number of sensors is large, and the detection cost is high. Contents of the invention [0003] An embodiment of the present invention provides a water detection device, which has a simple structure and can use one sensor to detect water content at different depths of soil. [0004] A moisture detection device is provided, comprising a strip-shaped detection body,...
